Stylisma pickeringii (Torrey ex M.A. Curtis) A. Gray var. pickeringii . Pickering's Dawnflower. Phen: Jun-Aug (-Sep); Jul-Sep. Hab: Longleaf pine sandhills, usually in the driest, most barren, deep-sand areas, occasionally colonizing dry, disturbed areas in sandhills, such as sandy roadbanks, known from the Fall-line Sandhills, aeolian rims of Carolina bays, and sandhills on relict riverine dunes along Coastal Plain rivers. Dist: Var. pickeringii ranges from s. NC south through SC, GA, AL, and e. MS, with a disjunct area in the Pine Barrens of s. NJ, sometimes treated as a separate variety "caesariensis" (see synonymy)
